The UE may start early measurement based on one or a plurality of the conditions. The UE may transmit a message (Msg 3) (e.g., an RRC connection request or RRC connection resume message) to the gNB at step 1f-30 while performing frequency measurement. Furthermore, the UE may receive a message (Msg 4) (e.g., an RRC Connection Setup or RRC Connection Resume message) from the gNB as a response to the Msg 3 and may be aware that the random access procedure is successful at step 1f-35, and may switch to the RRC connected mode step 1f-40. When the UE transmits a message (Msg 5) (e.g., RRC Connection Setup Complete or RRC Connection Resume Complete) at step 1f-45, the UE may include an indication that the UE has performed early measurement and frequency measurement results to be reported are present in the message, and may transmit the message. In the Msg 5, a new indication may be defined to indicate that early measurement results are present. rlf-InfoAvailable-r10 (e.g., an indication that an RLF has occurred and information to be reported is present) or logMeasAvailable-r10 (e.g., an indication providing a notification that measured information is present) already defined in the RRC message (RRC Connection Setup Complete or RRC Connection Resume Complete) may be used as the new indication.
